Title:
ELECTROLUMINESCENT-PHOTOLUMINESCENT HYBRID DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/173683
Kind Code:
A1
Abstract:
Disclosed are an electroluminescent-photoluminescent hybrid display device and a manufacturing method thereof. The electroluminescent-photoluminescent hybrid display device comprises a light guide substrate (10), a light-emitting layer (20) disposed on the light guide substrate (10), and a filter layer (30) disposed on the light-emitting layer (20), wherein the light-emitting layer (20) comprises an electroluminescent layer (21) and photoluminescent layers (22) disposed on both sides of the electroluminescent layer (21), a cathode (213) of the electroluminescent layer (21) is a semi-reflecting and semi-transmitting electrode, and an anode (211) is a transparent electrode. The electroluminescent layer (21) can emit blue light from both the cathode (213) and the anode (211). The blue light emitted from the anode (211) is irradiated onto the photoluminescent layers (22) through directional guidance of the light guide substrate (10), and excites the photoluminescent layers (22) to emit red and green light. The red and green light emitted by the photoluminescent layers (22) is mixed with the blue light emitted by the electroluminescent layer (21) to form white light. The white light is then filtered by the filter layer (30) to achieve a color display. The method of the present invention can increase the light utilization rate and color gamut of a display device.
